JOHN J. LAMB, OF DETROIT, MICHIGAN.

COMBINED KEROSENE VAPORIZER AND MANIFOLD.

Specification of Letters Patent.

Application filed February 19,1916. Serial No. 79,271.

To all whom it may concern:

Be it known that I, JOHN J. LAMB, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Combined Kerosene Vaporizers and Manifolds, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a partof this specification.

My invention relates to a combined kerosene vaporizer and manifold for internal combustion engines, as shown in the accompanying drawings and more particularly set forth in the following specification and claims.

One of the objects of my invention is to provide a simple and inexpensive device, by which kerosene or other hydrocarbon oils may be vaporized on their passage to the combustion chamber of an engine by the heat of the exhaust gases discharged from the latter, that it may be used as the principal fuel in the operation of an'engine.

Another object is to combine the device with a manifold connected directly with the inlet ports of an engine :the exhaust ports of the engine being also 'an integral part thereof, that it may thus receive not only the heat from the exhaust gases discharged from the engine, but the heat radiated from the cylinders. By thus combining the manifold with the vaporizer, the cost of manufacture and the space required tofinstall the device is materially reduced. A

Another feature of the invention consists in providing a plurality of conduits, relatively small in'cross section, but of extended length, around which the exhaust gases pass from the engine on their way to the muffler or other point of discharge;-thus the fuel is broken up in its passage that it may be exposed to the heat of the exhaust and receive the maximum radiation therefrom. These several conduits open at one end into a header where the gases conimingle and from thence pass directly into the manifold proper; whlch being connected adjacent to the intake ports of the respective cylinders, and contiguous to the several exhaust ports leading therefrom, serves as a superheater for'the gases prior to their entry into'the combustion chambers of the engine. j

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specifi'cationz- Figure 1 is aside elevation of the device, showing the main inlet conduit and the exhaustconduit broken away.

Fig. 2 is a longitudinal central section through the device shown in Fig. 1.

Fig. 3 is a cross sectional View through the device on line 3-3 of Fig. 1.

Fig. 4 is a cross sectional view on line H of Fig. 1.

Referring now to the letters of reference placed upon the drawings Patented Feb. 27, 1917.

A, denotes a chambered casting flanged at each end. 13, indicates a fuel inlet conduit bolted to one end of the casting connecting with a carbureter '(not shown)- adapted for both kerosene and gasolene.

C, is an arc-shaped casting bolted to the opposite. end :of the chambered casting A, having an upstanding wall C, spaced therefrom to form a header C ,the wall being perforated to receive andsupport a pluralityof pipes D. d, is a gasket lodged between the arc-shaped casting C, and the chambered casting A, and d, is a similar gasket between the latter and the flanged wall of the fuel inlet conduit B, to respectively provide a tight joint at these points. The pipes D, are supported at'their opposite ends in thimbles E, screwed into the end wall A,

fold F, with the respective cylinders of the 7 engine (not shown).

H, H H and H are ports connecting the exhaust ports of the engine with the chamber A H is an exhaust port leading from the chamber A to the muflier (not shown) or other point of discharge.

I, denotes Webs connecting the walls of the respective ports as indicated in Fig. 1-;-the webs having openings 1, for the passage of bolts to secure the device to the wall of the respective cylinders. Having indicated the several partsof my invention by reference letters, its construction and operation will be readily understood.

Following the usual practice in engines employing kerosene; or like oils for fuel, the engine is primarily started with gasolene as a fuel. Upon the vaporizer becoming header C it commingles and passes from thence into the manifold F, above, where it is super-heated by the heat radiating from the cylinder combined with the heat of-the exhaust gases passing down through the several ports H, lying adjacent to the manifold ;the fuel gas then passes through the inlet ports G, G, to the respective combustion chambers of the engine.

Having thus described my invention, what I claim 1s:

1. In a device of the character described, a casting having two independent chambers in adjacent relation, one of which is adapted to communicate with the inlet ports of an engine to serve as a manifold, therefor, a plurality of fuel pipes supported in the other chamber of the casting, an inlet conduit secured to one end of the chambered casting for'conducting fuel to said pipes, a header secured to the opposite end of the chambered casting and communicating with the manifold chamber of the latter to deliver thereto the gas discharged from said pipes into the header, a plurality of exhaust conduits integral with the chambered casting in adjacent relationv with the Wall of the manifold chamber and opening into the chamber in which the fuel pipes are lodged, and a conduit for the discharge of the exhaust gases from said last named chamber.

2. In a device of the character described, a casting adapted to besecured directly to the wall of an internal combustion engine having two independent chambers in adjacent relation to each other, one of said chambers serving as a manifold and adapted for direct communication with the inlet ports of an engine, a plurality of conduits integral with said casting and adjacent to the wall of the manifold chamber for connecting the exhaust ports of an engine with the other chamber of said casting, a conduit for the discharge of the exhaust from said last named chamber, a plurality of fuel pipes located within. said last named chamber, a header secured to one end of the casting adapted to establish communication between the pipes and the manifold chamber, and a fuel inlet conduit secured to the opposite end of the casting for the delivery of fuel to said pipes.

3. In a deviceof the character described, a casting adapted to be secured directly to the wall of an internal combustion engine having two independent chambers in adjacent relation to each other, one of which serves as a manifold and is adapted for direct communication with the inlet orts 'of an engine, a plurality of conduits integral with said casting and adjacent to the Wall of the manifold chamber to connect the exhaust ports of an engine with the other chamber of said casting, webs spaced from the wall of the chambered casting connecting the walls of said conduits together and perforated for the passage of bolts to secure the chambered casting to the Wall of an engine, a plurality of fuel pipes located within said last named chamber, a conduit for the discharge of the exhaust gases from the latter chamber, a header secured to one end of the casting adapted to establish communication between the pipes and the manifold chamber, and afuel inlet conduit secured to the opposite end of the casting for the delivery of fuel to said pipes.

In testimony whereof I sign this specification in the presence of two witnesses.
